The P4SMAJ18CA is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by Diotec. As an authorized distributor, Supreme Components International offers this reliable component for your circuit protection needs. This bidirectional TVS diode is designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a power dissipation rating of 400W and a breakdown voltage ranging from 18V to 20.5V. The P4SMAJ18CA is housed in a DO-214AC (SMA) surface-mount package, making it easy to integrate into your designs. Its fast response time and low clamping voltage ensure effective protection against overvoltage events. Ideal for various applications, including telecommunications, industrial equipment, and consumer electronics.
